Performance of Optimal Sensor Placement Strategies for Damage Detection in Civil Engineering
Structural Health Monitoring is an essential technique in civil engineering which deals with the detection of damages in structures with the use of different sensors data obtained. These sensors, such as acceleration, strain, temperature, etc., are to be attached to the civil structures at appropriate positions so that the structure can be monitored properly. This placement strategy of sensors is known as optimal sensor placement (OSP). The sensors are required to acquire the responses like acceleration, displacement, etc. of the structure to be monitored to determine its modal parameters. Effective OSP strategy is required to obtain the accurate modal parameters of the structure with optimum number of sensors. There are different OSP strategies, such as System—Realization Method and Optimization Method, which are applied by researchers for the damage detection of civil engineering structures. The objective of the study is to provide an overview of these OSP strategies and comment on their efficiencies. These strategies are based on the modal kinetic energy, Fisher Information matrix, retained independence information, linear independency of identified modes, etc. It is observed that EFI does not consider sensor noise.
